IMPROVEMENT INsAsn ANDsHUTTBn-PASTENINGS.

TO ALL WHOM IT MAY CONOERN Be it known that WILLIMJ. MILLER, of the city andcounty of Washington, in the District'of Columbia, have invented a new-and improved Mode of Securing Window-Shutters and Sash; and I do herehydeclare that the following is a. full Iand exact descriptionthereof, reference beinghad to theaec'ompanying drawings, and td the letters of reference marked thereon, in which like parts are indicated by like lettersirr the severa-l figur-es.`

The nature of my invention consists in a'certain device, lto be hereafter described, whereby'windowfshutters may be fastened, as also the sash;` saidlshutters and sash to be released` from the inside `of the windowll, and the sash may remain l'ocke'd whilst the shuttersareope'n. I

To enable others skilled in the art to make and use my invention, Iwill -p'rioceedto describe its construction' and operation.

Figure Irepresents a part-plan of'a lwindow-sill, sectionofs'hutter, as also of the fastening,v 85o., dto.

Figurer-2 is a. partial section f lower part of sash, as -also 'of the sill, on line t.y, u,nd the fastening ofthe sash; whilst- .Figure Sis an inside view'of shutter-fastening.`

In the` drawings, represents the window-sill, or a section of it. B' B, partial sections of the shutters. Gr,l a partial section of lower part of sash. a is a plate, attached to one of the shutters', liavinga projection, b, to pass through an opening inthe front ofv look, C, thus locking the shutter by means ot'projection b and pivoted har` e, upon the upper edge of which presses a spring,j`. Thel part d ot lock C is'sccured to' the first riser of thes'ill, against which 'the shutters close, whilst the part e is at right angles or is horizontal. g is "an angular projection, attached to and` underneath part c of lock C, one'facepf same 'being parallel to face d of the said lock. This angular projection serves as a guide to lock-bare, also as a bearing for the rod it, which also rests in the front face el of C. This 'rod tshould be squarewhere' it passes through the cam or elevator 1.' under the end of lock-bar e. L

When the rod h isturned so asrto throw the cam z' upwards, it raises the pivoted lock-bar e, .thus releasing the projection of platea, when the shutters can be opened. This positio'x'i'isshown in red lines in iig. 3." The projection 6 is As'o's'haped, that shutters can be closed and locked without it being necessary to turn the rod h, but they cannot be opened without turning said rod. l

The bar or-rod where it passes through' the cam t', has been said should be square, or of such shape as to turn the cam a' withoutthe'intrvention of a wedge or set-screw.

j is. a slotted plate, secured tothe sill A directly under the sash. It .has two downward projectionsthrough which the redit passes, and between which, on the said rod,-is a hook, c. .Thishook can be slipped on the rod.

t to suit'anywidth of sill. l'

lisanother slotted plate, secured to bottom rail'of sash G. It hasadownwad projection, which enters the slot in .platej, and over this do'virnrrard projection the hook Ic catches, as seen nvg. 2, locking the sash.

The' hook c is turned to the right or left at the same time that the cam c' is turned up or down.

When the shutters are closed and locked the sash is also locked, but after the shutters are opened the sash can be 'locked again. Fig. 2 shows the-sash loeked.-

Haring thusdcscribed my invention,rwhat I claim as new, and desire to secure vby Letters Patent of the United States, is

-The combination of theshutter-eatch 6,1001: C, rod L, hook lc, and platesl and j, or thevequivalents of said plates, constructed, arranged, and operated in the manner Vsubstantially as shown and described, and for the purpose of lockingor unlocking shutters and sash from within the room.'
